Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a grain inlet pipe mechanism for a grain dryer. Background Art
[0002] Grain dryer is a kind of equipment specially used to remove moisture from agricultural products. Its core function is to evaporate the moisture in agricultural products through heat energy and discharge it outside the machine through the exhaust system to achieve the drying effect. In order to inject grain into the grain dryer for drying and dehumidification, it is of great practical significance to develop a grain dryer inlet pipe mechanism.
[0003] Reference announcement number CN220959477U discloses a grain dryer inlet pipe mechanism, which includes a grain inlet pipe body, a second connecting piece, a buffer receiving plate, and a first spring. Three groups of second connecting pieces are symmetrically connected on both sides of the grain inlet pipe body. Buffer receiving plates are movably connected on both sides of the grain inlet pipe body through the second connecting pieces. A third connecting piece is fixed to the bottom of the buffer receiving plate. The buffer receiving plate is connected to a first spring through the third connecting piece. The other end of the first spring is connected to a fourth connecting piece. This mechanism reduces the contact force when the grain falls and contacts the buffer receiving plate by cooperating with the second connecting piece and the first spring, thereby buffering the falling force and preventing damage caused by direct falling of the grain. This effectively reduces the grain breakage rate. Multiple groups of buffer receiving plates and the connected first springs are provided to further enhance the buffering and protective effect of the grain. As can be seen from the above, although this grain inlet pipe mechanism can be well applied, it usually adopts a direct injection method to process the grain, which is not convenient for injecting the grain at a uniform speed, affects the injection effect of the grain, and often bothers users.

[0007] Preferably, a second motor is installed on the outer wall of one side of the conveyor frame, and one end of the second motor is connected to one end of the conveyor belt. The second motor is provided to drive the conveyor belt to operate.
[0008] Preferably, a first motor is installed on the outer wall of one side of the conveyor body, one end of the first motor extends into the interior of the conveyor body and is connected to one end of the spiral roller, so that the spiral roller is driven to rotate through the setting of the first motor.
[0009] Preferably, a guide bucket is rotatably mounted on the outer wall of the conveyor frame below the conveyor belt, and arc-shaped holes are provided on the outer walls on both sides of the guide bucket. The guide bucket is provided to guide the grain into the interior of the grain inlet pipe.
[0010] Preferably, a threaded pin is installed on the outer wall of the guide bucket at the position of the arc-shaped hole, one end of the threaded pin passes through the arc-shaped hole and is threadedly connected to the outer wall of the conveying rack.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the grain inlet flow pipe mechanism of the grain dryer not only ensures the grain inlet effect when the grain inlet flow pipe mechanism is used, but also expands the application range of the grain inlet flow pipe mechanism, effectively ensures the quality of the grain, and reduces the grain breakage rate;
[0012] (1) Grain is injected into the interior of the conveyor body through the feed port. As the first motor drives the spiral roller to rotate, the grain inside the conveyor body can be spirally transported to the right, so that the grain is transported to the right side of the conveyor body and falls to the top of the conveyor belt through the discharge port. As the second motor drives the conveyor belt to operate, the conveyor belt transports the grain to the right, and the guide bucket guides the grain to fall into the grain inlet pipe, so that the purpose of uniform speed injection of grain can be achieved, thereby ensuring the grain feeding effect when the grain inlet flow pipe mechanism is used;

[0014] (3) The buffer plate is elastically arranged on the inner wall of the grain inlet pipe by a spring member. When the grain falls into the interior of the grain inlet pipe, the buffer plate can contact the grain due to the elastic action of the spring member to buffer it, thereby reducing the phenomenon of the grain being broken when it falls directly into the pipe, thereby effectively ensuring the quality of the grain and reducing the grain breakage rate.
